CRISPR mines bacterial genome

Phys.Org (April 11) -- Using CRISPR-Cas9 gene-editing technology, researchers have now uncovered even more potential treasure hidden in silent genes. A new study from researchers at the University of Illinois and colleagues at the Agency for Science, Technology and Research in Singapore used CRISPR technology to turn on unexpressed, or "silent," gene clusters in Streptomyces, a common class of bacteria that naturally produce many compounds that have already been used as antibiotics, anti-cancer agents and other drugs.
